The documentation states:

该文件指出：

A notification's big view appears only when the notification is expanded, which happens when the notification is at the top of the notification drawer, or when the user expands the notification with a gesture.

通知的大视图仅在通知展开时出现，这种情况发生在通知位于通知抽屉顶部或用户使用手势展开通知时。

So my answer is no, you can't expand it by default.

所以我的答案是否定的，默认情况下你不能扩展它。

There is however a trick to push the notification to the top of the list where it would be expanded. Simply set the Priority to Notification.PRIORITY_MAXand chances are that your app's notification will make it to the top.

然而，有一个技巧可以将通知推送到列表的顶部，在那里它会被展开。只需将 Priority 设置Notification.PRIORITY_MAX为 ，您的应用程序的通知就可能会出现在顶部。

Notification noti = new Notification.Builder()
... // The same notification properties as the others
.setStyle(new Notification.BigPictureStyle().bigPicture(mBitmap))
.build();

You change

你改变

.setStyle(new NotificationCompat.BigTextStyle().bigText(th_alert))

along with the announcement

随着公告

notification = new NotificationCompat.Builder(context)

Here is an example:

下面是一个例子：

You can set Code

您可以设置代码

Intent intent = new Intent(context, ReserveStatusActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
NotificationManager notificationManager =
            (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
intent = new Intent(String.valueOf(PushActivity.class));
intent.putExtra("message", MESSAGE);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
stackBuilder.addParentStack(PushActivity.class);
stackBuilder.addNextIntent(intent);
// PendingIntent pendingIntent =
stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);

// android.support.v4.app.NotificationCompat.BigTextStyle bigStyle = new     NotificationCompat.BigTextStyle();
// bigStyle.bigText((CharSequence) context);

notification = new NotificationCompat.Builder(context)
    .setSmallIcon(R.mipmap.ic_launcher)
    .setContentTitle(th_title)
    .setContentText(th_alert)
    .setAutoCancel(true)
 // .setStyle(new Notification.BigTextStyle().bigText(th_alert)  ???????
 // .setStyle(new NotificationCompat.BigTextStyle().bigText(th_title))
    .setStyle(new NotificationCompat.BigTextStyle().bigText(th_alert))
    .setContentIntent(pendingIntent)
    .setNumber(++numMessages)
    .build();

notification.sound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
notificationManager.notify(1000, notification);

No need of doing any kind of modification in the any file for showing of multiple lines of Notification while using Push Notification V5, remove the field "style", from the object you are sending. Automatically the Multiple lines of notification will be seen. For more information, upvote the answer, ask your query. I will help you out.

使用 Push Notification V5 时，无需在任何文件中进行任何类型的修改以显示多行通知，从您发送的对象中删除字段“样式”。将自动看到多行通知。有关更多信息，请为答案投票，提出您的疑问。我会帮你的。

From this notification code you have got images, and big text or more.

通过此通知代码，您可以获得图像、大文本或更多内容。

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context);
            if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                mBuilder.setSmallIcon(R.drawable.small_logo);
                mBuilder.setColor(Color.parseColor("#D74F4F"));
            } else {
                mBuilder.setSmallIcon(icon);
            }

            mBuilder.setTicker(title).setWhen(when);
            mBuilder.setAutoCancel(true);
            mBuilder.setContentTitle(title);
            mBuilder.setContentIntent(intent);
            mBuilder.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION));
            mBuilder.setLargeIcon(BitmapFactory.decodeResource(context.getResources(), icon));
            mBuilder.setContentText(msg);
            mBuilder.setPriority(Notification.PRIORITY_MAX);
            if (Utils.validateString(banner_path)) {
                mBuilder.setStyle(notiStyle);
            } else {
                mBuilder.setStyle(new NotificationCompat.BigTextStyle().bigText(msg));
            }

            Notification noti = mBuilder.build();
            notificationManager.notify(0, noti);

notificationBuilder.setStyle(new NotificationCompat.BigTextStyle().bigText("Your Long Text here"))

simply setStyleof your notification builder.

只是setStyle您的通知生成器。
